The Mt. Wilson Fire sparked last week has been contained to 50 acres and is 70 percent contained, as ground crews assisted by aircraft continue to mop up, strengthen containment lines and monitor hotspots within the fire perimeter.

About 331 personnel remain in the fight in the mountains north of Pasadena, officials said late Sunday. 7 Hotshot crews, 14 Engines, 9 Bulldozers and 4 aircraft were assigned, officials reported earlier.
A prior infrared flight identified areas of heat within steep, inaccessible terrain in the fire area, so the threat remains throughout the Red Flag high temperature, low humidity weather event which started Sunday and continues through Tuesday.

Due to those high temperatures, mountain winds there’s still potential for the fire to grow outside of the containment area, officials said.

Virtually all trails and campgrounds in the red-hatched area shown above remain closed.

The forest area north of Altadena and Pasadena remains closed. With the fire danger and bulldozer crews working on the mountainside, potentially causing rocks to fall, the forest closure remains in effect.

There are several campgrounds on the border of the closure area.

The U.S. Forest Service closure order puts the following out of public reach: Echo Mt., Henninger Flats, Mt. Lowe Campground, Valley Forge Campground, West Fork Campground, Devore Campground, Spring Camp Campground, Millard Campground, and the Chaney Trail, as well as all of the trails and roads within the closure area.

Millard in now closed. Four bulldozers have been cutting new and expanding existing fire roads and firebreaks, officials said.
